UNIVERSITYLIBRARY mth/CLien-V nr Al nrrvr,, Welcome to A SCIENCE 2 Mo4 One Ie Li Science 24 contains four modules. You should work through the modules in order (from 1 to 4) because concepts and skills introduced in one module will be reinforced, extended, and applied in later modules.

Course Features The Science 14-24 Program The Science 14-24 program is designed for students whose needs, interests, and abilities focus on basic science understanding. This course sequence emphasizes scientific and related technological knowledge and skills that will enable you to understand and interpret the world around you. If you successfully complete each of these five-credit courses, you will meet the minimum requirement in science for an Alberta high school diploma. To support your development of scientific literacy, the Sciencel4-24 program provides a foundation of learning experiences to address the critical aspects of science and its applications. The following four foundations provide the general direction for Science 14 and Science 24: • Science, Technology, and Society (STS): You will develop an understanding of the nature of science and technology, the relationships between science and technology, and the social and environmental contexts of science and technology. • Knowledge: You will extend your knowledge and understanding of concepts in life science, physical science, and Earth and space science. • Skills: You will develop the skills required for scientific and technological inquiry, for solving problems, for communicating scientific ideas and results, for working with others, and for making informed decisions. • Attitudes: You will be encouraged to develop attitudes that support the responsible acquisition and application of scientific and technological knowledge to the mutual benefit of self, society, and environment. Consult your teacher or counsellor for information on Science 14 and Science 24. Also, if you have access to the Internet, you can find out more about Science 14, Science 24, and high school requirements at the Alberta Learning website. http://www.learning.gov.ab.ca 6 Science 24
